Your options are: 1. Use the rdma plugin and create rdma interfaces. 2. Use the DPDK plugin. The DPDK build that is generated when you build VPP will not include the mellanox PMDs by default. You need to explicitly enable them when you build. There are build variables named DPDK_MLX5_PMD and DPDK_MLX5_COMMON_PMD which have default values set to 'n'. Those need to be set to 'y' to build the mlx5 PMD. You can set these by running something like 'make DPDK_MLX5_PMD=y DPDK_MLX5_COMMON_PMD=y pkg-deb', or you could edit build/external/packages/dpdk.mk<http://dpdk.mk> and change the defaults there. -Matt On Fri, Dec 17, 2021 at 1:12 PM Varun Rapelly <vrape...@marvell.com<mailto:vrape...@marvell.com>> wrote: Hi, I’m trying to use ConnectX-5 NIC interfaces in VPP (20.09) application running on a x86 host (Ubuntu 18.04), but unable to find this interface in VPP.
